ISAIX16 OPERATING INSTRUCTIONS
1.
Insert the extender into an ISA expansion slot on an ISA
motherboard. Secure the extender to the system enclosure with
mounting bracket.
2.
Power up the system, SW1 switch can be in either position, all green
LEDs should light to show the state of the fused power.
3.
Test the extender by switching the SW1 switch up and down. The
red LED should be flashing with SW1 in up position, indicating bus
connection. The speaker should also buzz about once per second.
Adjust the volume of the speaker via the trim pot by the speaker.
4.
Add or remove add-on boards to the extender only when the
SW1 switch is in down position, the red LED is not flashing and
the speaker is not buzzing (bus isolated).
5.
Run test to the add-on boards with SW1 switch in the up position..
6.
To make current measurements without the fuse, remove the
corresponding plug fuse and place an ampere meter across pin 1
and pin 3 of the fuse socket pins. To make measurement with the
fuse, insert fuse at pin 2 and pin 4 of the socket pins, and connect
the ampere meter across pin 1 and pin 4 of the fuse socket pins.
7.
To make voltage margin tests without the fuse, remove the
corresponding plug fuse and connect external voltages to pin 3 of
the socket pin and connect external ground to system ground. To
make voltage margin with the fuse; move fuse to pin 2 and pin 4 of
the socket pins and connect external voltage to pin 4 of the socket.
Warning! Pin 1 of the fuse sockets should not be connected,
because they are tied directly to the system power.
8.
The green LEDs at the upper right hand corner indicate the status of
the fused power. If not lit, check the corresponding fuses and
replace them accordingly.
9.
To remove the adapter boards from the extender, one should be
careful not to lift the extender out of its system expansion slot. Keep
the extender down while removing the adapter board and make sure
the extender is turned off.
